Syntax:

      set terminal hp500c {<res>} {<comp>}

where C<res> can be 75, 100, 150 or 300 dots per inch and C<comp> can be "rle",
or "tiff".  Any other inputs are replaced by the defaults, which are 75 dpi
and no compression.  Rasterization at the higher resolutions may require a
large amount of memory.



=head1 hpgl

The C<hpgl> driver produces HPGL output for devices like the HP7475A plotter.
There are two options which can be set: the number of pens and C<eject>,
which tells the plotter to eject a page when done.  The default is to use 6
pens and not to eject the page when done.

The international character sets ISO-8859-1 and CP850 are recognized via
C<set encoding iso_8859_1> or C<set encoding cp850> (see C<set encoding> for
details).

Syntax:

      set terminal hpgl {<number_of_pens>} {eject}

The selection

      set terminal hpgl 8 eject

is equivalent to the previous C<hp7550> terminal, and the selection

      set terminal hpgl 4

is equivalent to the previous C<hp7580b> terminal.

The C<pcl5> driver supports plotters such as the Hewlett-Packard Designjet
750C, the Hewlett-Packard Laserjet III, and the Hewlett-Packard Laserjet IV.
It actually uses HPGL-2, but there is a name conflict among the terminal
devices.  It has several options which must be specified in the order
indicated below:

Syntax:

      set terminal pcl5 {mode <mode>} {<plotsize>}
          {{color {<number_of_pens>}} | monochrome} {solid | dashed}
          {font <font>} {size <fontsize>} {pspoints | nopspoints}

<mode> is C<landscape> or C<portrait>. <plotsize> is the physical
plotting size of the plot, which is one of the following: C<letter> for
standard (8 1/2" X 11") displays, C<legal> for (8 1/2" X 14") displays,
C<noextended> for (36" X 48") displays (a letter size ratio) or,
C<extended> for (36" X 55") displays (almost a legal size ratio).
C<color> is for multi-pen (i.e. color) plots, and <number_of_pens> is
the number of pens (i.e. colors) used in color plots. C<monochrome> is for
one (e.g. black) pen plots. C<solid> draws all lines as solid lines, or
'dashed' will draw lines with different dashed and dotted line patterns.
<font> is C<stick>, C<univers>, C<cg_times>, C<zapf_dingbats>, C<antique_olive>,
C<arial>, C<courier>, C<garamond_antigua>, C<letter_gothic>, C<cg_omega>,
C<albertus>, C<times_new_roman>, C<clarendon>, C<coronet>, C<marigold>,
C<truetype_symbols>, or C<wingdings>. <fontsize> is the font size in points.
The point type selection can be the standard default set by specifying
nopspoints, or the same set of point types found in the postscript terminal
by specifying pspoints.

Note that built-in support of some of these options is printer device
dependent. For instance, all the fonts are supposedly supported by the HP
Laserjet IV, but only a few (e.g. univers, stick) may be supported by the HP
Laserjet III and the Designjet 750C. Also, color obviously won't work on the
the laserjets since they are monochrome devices.

Defaults: landscape, noextended, color (6 pens), solid, univers, 12 point,

          and nopspoints.

With C<pcl5> international characters are handled by the printer; you just put
the appropriate 8-bit character codes into the text strings.  You don't need
to bother with C<set encoding>.

HPGL graphics can be imported by many software packages.



=head1 hpljii

The C<hpljii> terminal driver supports the HP Laserjet Series II printer.  The
C<hpdj> driver supports the HP DeskJet 500 printer.  These drivers allow a
choice of resolutions.

Syntax:

      set terminal hpljii | hpdj {<res>}

where C<res> may be 75, 100, 150 or 300 dots per inch; the default is 75.
Rasterization at the higher resolutions may require a large amount of memory.

The C<hp500c> terminal is similar to C<hpdj>; C<hp500c> additionally supports
color and compression.



=head1 hppj

The C<hppj> terminal driver supports the HP PaintJet and HP3630 printers.  The
only option is the choice of font.

Syntax:

      set terminal hppj {FNT5X9 | FNT9X17 | FNT13X25}

with the middle-sized font (FNT9X17) being the default.



=head1 imagen

The C<imagen> terminal driver supports Imagen laser printers.  It is capable
of placing multiple graphs on a single page.

Syntax:
